From Waste to Resource: Smarter Handling for Off-Grid Toilet Systems
A good off-grid toilet solution does not end with the toilet itself. What happens after use is just as important. Whether you have a urine-diverting toilet at a cabin, summer house, garden building, or remote property, the right handling system can make everyday use simpler, cleaner, and more sustainable.
With Separett’s supporting products, urine and toilet waste can be managed in a practical way. Separett Ejectortank makes it possible to reuse diluted urine as plant fertilizer, while Roslag helps turn toilet waste into compost. For those who prefer infiltration instead of collection or reuse, Ecovault can also be used as a simple underground solution for urine and light greywater.
Together, these products help create a more complete off-grid system — one where waste is not only handled, but also given a purpose.
Turning Urine into Plant Fertilizer
Urine contains many of the nutrients that leave the body, and when diluted correctly, it can become a valuable fertilizer for plants. Separett Ejectortank is designed to mix urine with water in the right proportion: approximately 8 parts water to 1 part urine. This creates a diluted mixture that plants can absorb without being damaged.
The Ejectortank is especially useful for urine-diverting toilets, where urine is collected separately. Once the tank is full, it is connected to a regular garden hose. Water then mixes with the urine inside the tank and creates ready-to-use fertilizer that can be sprayed over areas such as lawns, shrubs, and garden beds.
The 50-litre tank is suitable for leisure homes. A float indicator shows when the tank is full, making it easy to know when it is time to empty. The included hose also makes it simple to spread the mixture over a larger area.
The product is easy to assemble and has no moving parts. For correct function, it requires a water pressure of at least 2.5 bar.
Composting Toilet Waste the Simple Way
When using a waterless or urine-diverting toilet, solid waste needs to be handled safely and responsibly. Roslag is a durable composting container designed for composting toilet waste, making it a practical part of a complete off-grid toilet setup.
Thanks to its tight-fitting lid, Roslag can be used not only for toilet waste, but also for kitchen and garden waste. This makes it a flexible composting solution for cabins, gardens, and properties where you want to manage organic waste in one place.
For many off-grid homes and holiday cottages, Roslag provides a natural next step after using a dry toilet. Instead of relying on sewage systems or frequent waste transport, the waste can be collected and composted in a controlled way over time.
A Simple Option for Infiltration
While the Ejector Tank and Roslag focus on reuse and composting, some installations may need a solution for infiltration instead. This is where Ecovault Infiltration Chamber can be a useful addition.
Ecovault is an underground infiltration chamber designed to disperse urine from urine-diverting toilets into the soil. It can also handle light greywater from showers and bathroom sinks when the system is correctly sized. It is made as a modern alternative to traditional hand-dug gravel soak pits, using a lightweight and modular chamber system instead.
This makes Ecovault a good option for cabins, tiny homes, remote structures, and other places without access to municipal sewer systems. It is not the main focus when the goal is to reuse nutrients, but it can be a practical solution when infiltration is the better choice for the property.
Creating a More Complete Off-Grid System
The best off-grid toilet setup depends on how the toilet is used and what the property needs. For urine, Separett Ejectortank makes it possible to reuse nutrients in a simple and controlled way. For solid waste, Roslag offers a dedicated composting solution. And when infiltration is preferred, Ecovault can help disperse urine and light greywater underground.
Together, these products show that off-grid waste handling does not have to be complicated. With the right system, urine and toilet waste can be managed in a cleaner, smarter, and more sustainable way — helping make cabins, gardens, and remote homes more practical for everyday life.
